Waste, Oil and Chemical Spills Management

Importance

(GRI 3-3a., GRI 3-3b.)

Ineffective waste management results in substantial costs associated with entire waste management process entire. In addition, the volume of waste generated by the industrial sector in Thailand continues to increase each year. Without appropriate waste management approaches by industry, this trend may adversely affect public health, livelihoods, and the environment. Moreover, the increasing enforcement of the Extended Producer Responsibility regulations (EPR) reflects growing pressure on businesses to reduce the impacts of their operations, particularly in relation to packaging and waste management, in ways that are measurable and tangible.
recognizes the impacts arising from resource use and waste generation throughout the value chain, from upstream to downstream activities. Accordingly, OR places strong emphasis on waste management, including the management of oil and chemical spills, to mitigate environmental and health impacts. At the same time, OR seeks to create positive value by promoting the use of circular resources, enhancing safety knowledge within communities, and strengthening engagement among employees and stakeholders.

Management Approach

(GRI 3-3c., GRI 3-3d., GRI 3-3e., GRI 3-3f)

Waste Management
OR set the quantified targets to minimize waste for all operations which is a zero hazardous and non-hazardous waste disposal sent to secure landfill in order to reduce the waste sent to landfill. In 2025, to enhance waste management effectiveness, OR conducted waste assessments /audit, according to ISO 14001 to identify opportunities for improving waste performance. In addition, during 2024–2025, OR developed a database system for collecting data on waste generated at OR’s establishments, as part of the OR ESG Data Platform, to enable systematic monitoring of waste quantities across its operations.

Types of Waste and Waste Management Guideline
The majority of raw materials utilized in OR’s businesses are oil, LPG, base oil, coffee beans, mixing powder, and baking flour, which are processed into products for customers and consumers through the OR business’ value chain. This results in the following primary types of waste; oil sludge, oil-contaminated materials, coffee chaffs, breadcrumbs, and defect mixing powder, all of which, without proper management, could lead to environmental impacts.
OR’s activities result in the generation of various types of waste. Therefore, OR has established management guidelines for each waste type, integrating these guidelines into each of OR’s business as shown in the table below:

Business Types	Significant Types of Waste	Potential Impacts	Waste Management Guideline

For non-recyclable waste, OR has measures to ensure that waste are properly disposed of by a licensed disposer as legally required. The licensing companies who collect waste from OR’s operation will clearly identify the reuse or recycling methods to ensure zero waste to landfill. The amount of waste diversion to landfill and the disposal methods will be then reported and verified by an independent accredited body via annual sustainability verification and assurance. In 2025, OR achieves the zero waste-to-secure-landfill target for both hazardous and non-hazardous waste.
Apart from the programs to reduce and eliminate waste from operations, OR also provides Lean Six Sigma waste reduction training to employees. The objective of the training program is to apply Lean Six Sigma principles to reduce costs/expenses, leading to higher production efficiency and waste reduction in OR’s operations.

Oil and Chemical Spills

As one of OR’s businesses is in the oil industry, oil and chemical spills may occur, which could severely affect the environment and nearby communities, as well as adversely impact OR’s business. Therefore, OR places great emphasis on preparing to respond to oil and chemical spills. Oil spill response equipment has been installed to handle such incidents, and regular inspections are conducted to ensure its readiness in all areas. Annual emergency response drills are held for oil depots, petroleum terminals, and aviation depots, enabling OR to respond promptly when spill incidents occur. Furthermore, OR collaborates with the members of the Oil Industry Environmental Safety Group Association (IESG) to raise funds for the purchase of equipment that can respond to increasingly severe spill incidents.

Opening of the ‘OR Oil Spill Response Training Center’
OR officially opened the “OR Oil Spill Response Training Center” at the Saraburi Oil Depot, Sao Hai District, Saraburi Province, marking an important step in raising safety standards and environmental protection in Thailand’s oil and gas industry.
This “OR Oil Spill Response Training Center” is equipped with comprehensive, state-of-the-art equipment and facilities. These include a large water basin covering 1,500 square meters for practical training, various types of oil booms with a total length exceeding 100 meters, oil skimmers powered by hydraulic engines, sea spray oil dispersant equipment, a 1,200-liter floating storage tank, an 11,000-liter fast tank for liquid storage, and an oil spill response boat. This demonstrates OR’s commitment to environmental protection and operational safety, particularly in addressing oil spill incidents. With OR’s oil terminal located near several water sources, the company recognizes the importance of preparedness in effectively responding to emergencies.

In addition, OR has adopted the PTT Group’s environmental remediation guidelines for spill incidents affecting the environment and applies these guidelines in environmental restoration efforts when such incidents occur. In 2025, no significant spill incidents were reported at OR’s establishments.

Performance

Waste management

OR accelerates waste reduction throughout its value chain by promoting action plans to reduce waste generated in production processes within each business group, as follows:
Waste management in the Lifestyle business group

1. Sustainable Coffee Project
OR reduces waste generated from production processes through the Sustainable Coffee Project by providing training for farmers on coffee cultivation, maintenance, harvesting, and processing. These efforts help improve the quality of raw materials entering the production process, thereby reducing substandard inputs and minimizing waste generated during production.

2. Feasibility study on the reuse of coffee husks and parchment
OR invests in innovation and research and development (R&D) to minimize waste. Examples include research into the use of coffee husks and parchment as alternative materials for mushroom cultivation, demonstrating the beneficial reuse of waste generated from production processes. In addition, OR is conducting a feasibility study on the utilization of coffee husks and parchment, which are by-products of the coffee hulling process at the coffee bean processing facility in Chiang Mai Province. The study covers analyses of the chemical and physical properties of coffee husks, as well as their potential use as agricultural soil amendments. This initiative reflects OR’s commitment to promoting the circular economy by adding value to agricultural waste.

3. Food Loss to Fertilizer
The Food Loss to Fertilizer Project collects food loss from the production process of the Café Amazon business, such as coffee chaff from the Café Amazon Roastery Plant. In 2025, the Food Loss, which is the coffee chaff, were used to produce the soil amendment materials. In addition, a study has been conducted on the use of parchment coffee husk, a waste product from the coffee bean processing in Chiang Mai province. The study explores various ways to utilize the husk, such as analyzing its composition and investigating its potential as a soil amendment material for plant cultivation.

4. Lean Six/Sigma project at Dry Mix Factory
The Lean Six/Sigma project focuses on finding ways to reduce or eliminate unnecessary activities or those that do not add value, with an emphasis on reducing uncertainty and ensuring stable operations with minimal variation. The project was implemented at the Dry Mix factory, and the results led to more accurate final product release processes. This resulted in a reduction in the amount of waste generated from packaging during the process.

5. Hand Cream Research Project
OR conducted research on waste from green coffee beans or black coffee beans that are unsuitable for roasting for coffee consumption, with the objective of creating added value by developing commercially viable products within OR’s business portfolio. This research led to significant value creation from black coffee beans through the development of personal care products derived from black coffee bean extracts rich in bioactive compounds, such as chlorogenic acid, phenolic acids, and flavonoids, which offer benefits including wrinkle reduction, anti-inflammatory effects, and skin moisturization.
In addition, OR further enhanced these extracts by converting them into nano-sized particles to preserve the efficacy of the active compounds and to facilitate deeper skin absorption, promoting healthy and radiant skin from within. As an initial step, OR developed a hand cream product to demonstrate OR’s potential and commitment to reducing waste from business operations in line with the OR 2030 Goal. In the future, OR plans to further develop nano-particle extracts from black coffee beans into higher value-added products, such as serums and cosmeceuticals, as well as to advance environmentally friendly extraction technologies to generate sustained economic and environmental value.

6. Project to Reduce Waste Disposal through Recycling at Café Amazon Lifestyle Business Center (OASYS)
OR recognizes the importance of waste generation and waste reduction in production processes, particularly in the operations in Café Amazon Lifestyle Business Center (OASYS), which generates a significant amount of operational waste, such as paper packaging, plastic packaging, and aluminum foil. The disposal of such waste has traditionally relied mainly on conversion into alternative fuel, with the potential for a portion to be ultimately disposed of through landfilling.
To align with corporate targets and to place greater emphasis on appropriate end-of-life waste management, including reducing the volume of waste sent to landfill, OR has collaborated with PRISM and GC to segregate recyclable waste and channel it into recycling processes through legally licensed waste management contractors. This initiative helps reduce waste requiring disposal, promotes the use of circular resources, enhances waste utilization, and contributes to lowering environmental pollution resulting from incineration.

Waste management in the Mobility business group
